- Joseph, in the county of Berrien and State of Michigan, have invented a new and useful Crate-Side Machine, of which the following is a specification. v

This invention relates to machines of that class employed in the manufacture of crate I or box sides, and has for its principalohject to provide a means wherebythc longitudinal and cross slats of the side may be held in properly spaced and crossed relation, and

v automatically fed'to a stapling or other machlne for fastening the slats together.

A further object of the invention is to nrovide. a carrying frame, or form. formed of light metal, and of such shape as to hold the members of the side in proper relative posizo tions, these forms or frames being then fed to the machine and operated upon automatically to present the successive cross slats beneath the stapling or other securing mechanism.

A still further object of the invention is to provide a novel construction or slat holding orm or frame that is ntovidcd with edge recesses for the reception of the longitudinal bars or slats of the side;-and with a series of recesses or notches to receive and hold the cross slats in pro ierly spaced relation.

With these an other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of )arts, hereinafter fully described, illustrate in the acoompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and'niinor details of the structm'e..ina y' be made without departing 1m n the's irit or sacrificing any of the advantages o the invention. "In the accompanying drawings :Figure in perspective view of a crate side formmg machine constructed in accordance with the invention. Fig.2 is a transverse sec- 'tional view of the same. plan view on the line 3-3 of Fig. 2 drawn to an enlarged scale. Fig. 4 is a transverse section on the line-451 o'fFig. 3.

throughout the several figures of the drawings.

The working parts of the machine aresupported on a suitable framethat includes a pair of cheek plates or standards 10 that are connected by transversely disposed bars 11 and 12 and a platform or table 13. The two bars 11 and 12 are provided with dove tailed slots 14 for the reception of similarly shaped ribs carried by stapling mechanisms X. .As the construction of the stapling devices forms no part of the present inventioii, they have not been illustrated in detail. lhcse stapling devices may be adjusted in the direction of the Width of the machine tor the purpose of placing them at any point and at any distance from each other. within the ca )acity of the machine.

In the ower )ortion of the frame are journalcd two shat s 17 and 18,. the shalt 17 l)(. ing driven from any suitable source of power. and communicating motion to the shaft 15 through gearing 19. This 'shaft ifl projects beyond the outer sides of the frame and car ries eccentrics which are connected by rods 20 to the stapling devices. The general oporation of machines of this ty e is well known and detailed description is, t erefore, unnecessary.

The platform or table 1.; is provided with a pair of transversely extending dove tailed grooves 22 for the reception oi correspond- &

.mgly snapcd ribs that depend from the lower side of a pair of guide-bars 23, so that said bars may be adj usted independently of each other, and made to correspond to the posi tions assumed by the stapling devices.

The upper face of each bar is provided \\'i th a long groove or channel 24, that extends from end to end thereof and in this groove or channel .fi ts a slidable bar 26, carrying a pivotcd pawl 27 that is arranged to engage With openings .28 formed in the outer side of a carrying form or frame 29. The slidable bar-26 is held down in place byza'suitable cover plate 30 Which may be readily removed should occasion require.

The rear ends of the slidable bars 26 are connected to the upper ends of a pair of levers 32 by means 0: rods 33, said rods carr'y ing or including in their construetion sections provided with right and left hand screw threads, so as to permit accurate adjustment oi the length of the rods. The lower portions of the levers 32 m rigidly connected together through a rock shaft'32', and one of said levers is pivotally connected to the outer end of a rod 34 carrying at its inner end an eccentric strap 35 that surrounds an eccentric or cam 36 locked on the shaft. 18. The lever 32 is provided with an arcuate slot 37 inovhich the pivot bolt 38 may be adjusted therefrom as may be necessary to permit the insertion of the end strips or battens 3 which may be held in place by small friction springs 40 secured to the strips 40. The space between each strip 40 and the adjacent side of the frame is of sufficient Width to receive battens of the largest size and when smaller battens than usual are employed filling strips y are intrmlu ed'. trips 40 are provided with recesses 41 spaced from each other, and of )ropcr length to re cci've the cross slats Z which have been laid in' place within the notches or recesses and littcd over the end slats or battens in readiness for the stapling ornailing operation.

in pract 'c, the forms or frames are prefcrnblv laid on a table immediately in advuucc of the table 13, and the longitudinal nmlcross slats arc then placed in proper position within the form or frame, after which the frame is forced ahead until it enters between the two guide-bars 33. The operator pushes the frame forward a distaiice sullicicnt to permit the feeding pawls to engage with the lirst set 'of openings 28 and as the pants are actuated they move the frame forward thc rcquircd distance in order toprcsent the lirst cross slat undcr thc stapling or riveting devices. These fastening devices thcu operate to drive staples, nails or lllit fastening devices through the lirst cross slat and the longitudinal slats or battens. 'lhe pawl automatically dis-engages from the lirst set ofopcnings and is then movcd to engage the second set of openings, the operation continuing until thc frame is entirely throughthcnmchinc,andtherebcingasmany feeding operations as there are cross slats.

readiness for a second operation of the malhis arrangement permits the ad- The upper edges of thel it will )c noted that after the opcrator has chine, so that the latter may be kept continuously at Work. A

In some cases it ma be desired to vary the feed to a considerable extent and to accom lish this a crank disk 36 may be placed on t e end of the shaft 18 at a point outside the frame. This disk is provided with a dia-s metrically extending groove 50, the walls of which are undercut to receive the head of a crank pin 51; the crank pin is thus rendered ad'ustable.

n the end of the rock shaft 32 secured "an arm 53 which is connected by a rod 54 to 1 crank pin 51 so that the throw of the lever 32 may be readily allowed to secure the desired feed.

What is claimed is:-

l. A crate side holding-and carrying frame comprising side and end members and open at top and bottom, longitudinal strips paral-.

lelvvith and spaced from the side members forthe reception of the longitudinal bars or battens, said strips being provided with means for holding the cross slats in properly spaced relation.
